Correct option is D
Decreasing connotation means arranging terms from the most specific to the most general.
Let us analyze the terms:
Square: A specific type of rectangle with all sides equal and all angles right.
Rectangle: A type of polygon with four sides and four right angles.
Polygon: A broad category of closed figures with straight sides.
Geometry: A branch of mathematics that includes the study of polygons and many other figures.
So, from most specific to most general, the correct order is:
Square → Rectangle → Polygon → Geometry
Therefore, the correct arrangement is:
D – B – A – C
